Solutions for high temperature applications

It gets hot in the combustions and
exhaust stream areas of large engines â€“ temperatures of several hundred degrees
(centigrade) are common. Materials used here must have the appropriate
temperature resistance. The same is of course valid for screws and connecting
elements.

We therefore offer our customers special
screws for high temperature applications of up to 900 degrees centigrade in a
variety of material grades. We can quickly and cost-efficiently produce such
temperature resistant fasteners, especially for large engine applications, in
diameters of up to 30 mm and lengths of up to 400 mm.

Typical applications of our special screws in large engines:

Turbo chargers

Manifolds

Motors

Exhaust systems

Flange connections

Catalytic convertors

Heat shields
